Title: Luminance signal/chrominance signal separator
Inventor: MOTAI MASAHIKO
IPC: H04N9/78
Filed: 1992-01-30
Abstract: PURPOSE:To improve picture quality by suppressing folded distortion and ringing. CONSTITUTION:A color demodulator 31 demodulates an input composite video signal band-limited by a BPF 51 based on a clock from a B-LOCKPLL 18. A pulse HBL from a digital H-PLL 50 is supplied to a latch circuit 52, and the latch circuit 52 supplies the pulse HBL by synchronizing with an fsc clock to a memory control circuit 19. A thinning processing circuit 35 performs the thinning processing of demodulated output by supplying the clock synchronized with the fsc clock from the memory control circuit 19. Thereby, the thinning processing of a thinning phase can be performed without requiring fixed interpolation processing, which prevents the folded distortion from being generated. A chrominance signal frame-separated by an adder 38, after to which the interpolation processing being applied by an interpolation LPF 41, is color-modulated. The modulated output is subtracted from the input composite video signal, and a luminance signal can be separated.

Title: Growth of heteroepitaxial blue light-emitting gallium nitride
Inventor: RII SAN SOKU
IPC: H01L21/20
Filed: 1995-01-05
Abstract: PURPOSE: To heteroepitaxially grow blue light emitting GaN on the surface of a sapphire single-crystal substrate, using a coherent laser by a vapor-phase epitaxial method. CONSTITUTION: First, an AlN thin film layer is deposited on the interface between the surface of a substrate and a gallium nitride active layer. Then, utilizing a resonant light decomposition reaction between a gallium-containing organic metal precursor such as trimethylgallium and the nitride containing a reactor such as ammonia, a monolithic GaN thin film of about 2 to 30 μm in thickness, having an wurtz ore type crystal-lattice structure, is grown epitaxially. As a result, a blue light emission GaN thin film can be obtained at a temperature in the neighborhood of 800 deg.C, which is lower than the conventional temperature, and under a vapor pressure of 0.1 to 3.8 mmHg (0.1 to 3.8 Torr) which is considerably lower than the conventional vapor pressure.

Title: Mass flowmeter
Inventor: HONDO MASANORI
IPC: G01F1/32
Filed: 1991-02-06
Abstract: PURPOSE:To reduce the error of a mass flowmeter to a binarization error only so as to improve the accuracy of the flowmeter by generating the control signal of the switch of a variable gain amplifier by binarizing the pulse of a vortex frequency. CONSTITUTION:A vortex signal converted from a measured flow rate is changed by means of a digital control signal which is outputted from an adder circuit and used by a variable gain means to change a circuit gain in inverse proportion to the frequency of the vortex signal and the mass flow rate signal corresponding to a measured flow rate is outputted by detecting and rectifying the vortex signal. A pulse signal P1 through a Schmitt trigger 45 is inputted to a PLL circuit 50 and fed back after its frequency is divided by means of a 1/N counter 51, resulting in N-times enlargement of the frequency. A binary counter 52 binarizes the signal P1 and latch circuit 54 latches the binarized signal. The output e3 of the adder circuit is connected to the circuit 54 through resistances R1-Rn and outputted to a detection/rectifier circuit through a variable gain amplifier 56. The amplification degree of the amplifier 56 is inversely proportional to the vortex frequency and changed by means of the output of the circuit 54. Since the control signal of the switch of the amplifier 56 is generated by binarizing the pulse of the vortex frequency, the error of the variable gain means can be eliminated except a binarization error.
